Claims (7)
einer drehbar gelagerten Gewichtsausgleichswelle (1), auf der eine Seiltrommel (2) mit einem an das Torblatt (3) angeschlossenen Zugseil angeordnet ist,
einer Torsionsfeder (5), die an einem Federende an der Gewichtsausgleichswelle (1) befestigt ist, und
einer Fangvorrichtung (6) zur Verhinderung eines Ab sturzes des Torblattes (3) bei einem Bruch der Torsionsfeder (5),
wobei die Fangvorrichtung (6) ein auf der Gewichtsaus gleichswelle (1) angeordnetes Klinkenrad (7) sowie ein Sperrelement (8) aufweist, das bei einem Bruch der Torsionsfeder (5) in das Klinkenrad (7) einfällt und dadurch die Gewichtsausgleichswelle (1) arretiert, da durch gekennzeichnet,
dass das Sperrelement (8) einen von der Torsionsfeder (5) durchfassten ringförmigen Träger (9) aufweist, der um eine zur Gewichtsausgleichswelle (1) parallele Drehachse (10) schwenkbar an einer Konsole (11) gela gert und an einem zur Drehachse (10) gegenüber liegenden Trägerabschnitt mit dem freien Federende der Torsionsfeder (5) verbunden ist,
dass das Sperrelement (8) unter der Wirkung der gespannten Torsionsfeder (5) an einer Anschlagfläche der Konsole (11) anliegt und
dass an dem Träger (9) ein Sperrglied (12) angeordnet ist, das sich in Achsrichtung über den Bereich des Klinkenrades 1 (7) erstreckt und bei einer durch einen Federbruch ausgelösten Schwenkbewegung des Trägers (9) in das Klinkenrad (7) einfällt.1. Weight compensation device for an overhead movable door leaf, with
a rotatably mounted counterbalance shaft ( 1 ) on which a cable drum ( 2 ) with a pull cable connected to the door leaf ( 3 ) is arranged,
a torsion spring ( 5 ) which is attached to the spring of the balance shaft ( 1 ) at one end of the spring, and
a safety device ( 6 ) to prevent the door leaf ( 3 ) from falling if the torsion spring ( 5 ) breaks,
The catching device ( 6 ) has a ratchet wheel ( 7 ) arranged on the counterbalance shaft ( 1 ) and a locking element ( 8 ) which falls into the ratchet wheel ( 7 ) if the torsion spring ( 5 ) breaks, thereby causing the counterbalance shaft ( 1 ) locked because marked by
that the blocking element ( 8 ) has an annular support ( 9 ) which is encompassed by the torsion spring ( 5 ) and which is pivotable about a rotation axis ( 10 ) parallel to the weight balancing shaft ( 1 ) on a bracket ( 11 ) and on one to the rotation axis ( 10 ) opposite carrier section is connected to the free spring end of the torsion spring ( 5 ),
that the locking element ( 8 ) bears under the action of the tensioned torsion spring ( 5 ) on a stop surface of the bracket ( 11 ) and
that a locking member ( 12 ) is arranged on the carrier ( 9 ), which extends in the axial direction over the area of the ratchet wheel 1 ( 7 ) and falls into the ratchet wheel ( 7 ) when the carrier ( 9 ) pivots due to a spring break.
